Specification of Letters Patent.

Application filed ctober 24, 1908. Serial No. l159,361.

To all whom' tf/nay concern.'

Be it known that I, CHESTER CHARLES J ONES, a citizen of the UnitedStates, residing at Beatrice, in the county of Gage and State ofNebraska, have invented a new and useful VGrasolene-Engine, of which thefollowing is a specification.

`.My `invention relates to internal combustion engines, as4 gas andgasolene engines; and the objects of my invention are to produce anengine having'a superior method of compressing and retaining theexplosive charge, and also a superior method of interi'o'r coolinO theseresults by the mechanism illustrated in the accompanying drawings, inwhich- Figure 1 is a vertical section, showing the at one extremity ofits stroke. Fig. 2 is a like vertical section, showing the piston at theother extremity of itsstroke. Fig. 3 is asection on the line 3 8 of-Fig. 1. Fig. L1 is a section on the line 4-4 or' Fig. l-. Fig. 5 is asection on the line 5-5 of Fig. 1, and Fig. Gis a section on the line(3*6 of Fig. 1.

vSimilar figures refer to similar throughoutwthe several views.

My device, as here illustrated, is a gasothe two cycle type andreferring to the drawings may be described as followszel i 1 is thecranlccase, and v V the engine shaft of the engine. #L

4 is the crank pin and .l rod, having a wrist-pin 21. i

S is atwo-part piston, hai/ing compression rings 9 on its upper pistonhead 11.

10 is an auxiliary piston, formed integral with the upper piston-head,and is provided with compression rings 12. It acts as a plunger ashereinafter described. Surrounding the piston is a eylinder 6, providedat one end, for a portion of its length with a raised interior wall 7,forming a lower interior compression cham ber 14 within the cylinder. I

13, 13, are cooling ribs upon the interior sur ace of the piston, havingchannels 15 between the'ribs through and over which air or other coolingHuid may be forced as hereinafter set forth.

16 is a port in the byepass 17, in the wall 18 is the upper port partsthe connecting piston opening to the of the cylinder. and 19 the lowerport `the suction stroke, for the engine. I achieve' of the 1oy-pass 1.722 is the 'spark-plug openlng. i

19 is anlexhaust port,'and 2O an intake port,-both through the walls ofthe cylinder.

It will be observed that`the lower and auxiliary piston 10, is providedwith compression rings 12, the Same as the piston head 11; but the walls7 of its cylinder are contracted so as to allow the upper piston totelescope them, on its downward stroke, thus compressing the gases whichhave been taken into the chamber at ,the intake port 20 by and holdingthem compressed in the compression chamber 14 until the port 16 openingin the wall of the piston meets the lower port 19 of the by-pass whenthey are allowed to enter the cylinder above the piston through theupper port 18 of the by-pass 17.

In orderto reach the by-pass the compressed gases must pass around oneside of the piston across the piston-head 10 and halfway down on theother side to the opening 16, in the wall of the piston.

The piston has a partition 111 with an opening only on the opposite sidefrom t-he port-opening 16. y This forces the mixture of gas and air bythe route described and it will be observed that the annularconipression chamber .is entirely closed below the inlet port 20 so thatthegas canne escape therefromv and the compression will be thorough.

' Formed on the interior oi the piston, preferably longitudinallythereof, are coolingribs '13 and channels 15 between `the ribs for thepassage of acooling Huid, as air, or air and gas.` ln operation everyimpulse throws the fresh air and gas around the inner walls of thepiston with such velocity that the piston is cooled.

lVhat I claim and desire to secure by Let.- ters Patent of the UnitedStates is hydrocarbon engine comprising Icon# centric cylinders formingan annular compression chamber closed except at its upper end, an intakein the outer cylinder above the upper end of the inner cylinder, anexhaust in the side of the outer cylinder. a bypass disposedlongitudinally on the side of the outer cylinder with its ends betweenthe planes of the intake and the exhaust, concentric pistons arrangedwithin the cylinders,

' the upper end of the outer piston being above and spaced from theupper end of the inner In testimony that I claim the foregoing aspiston., and a transverse partition eonnecting my own, I have heretoaffixed my signature the upper end of the inner piston with that in thepresence of two Wltnesses.
